Call to Duty (Rank 2) Edit
Any spirit the Philodox knows by name is a potential servitor. With this Gift, the werewolf can summon and command any spirit she knows by name. Only one command is possible at a time, and the spirit departs after fulfilling the one request. An Incarna avatar teaches this Gift.
Silent Striders of the Wayfarers camp may also learn this Gift. Wayfarers are quite prone to negotiating terms with spirits, as well as asking for the names of particular spirits as payment for their services.
Obviously, the Philodox must learn the spirit's name, which usually requires personal acquaintance or use of the Gift: Name the Spirit. The player rolls Charisma + Leadership (difficulty of the spirit's Willpower). If the player spends two Gnosis points, the werewolf can summon all Gaian spirits within one mile to protect or assist her, even if she does not know their names.
